To make glacier for a science project, empty the contents of an 8-ounce bottle of glue into a bowl. Refill the glue container with warm water, shake, then pour the water into the bowl. Add 2 drops of blue food coloring. In a plastic cup with 1/2 cup warm water, dissolve 1 teaspoon of borax powder. Slowly add this solution to the glue mixture while stirring to form glue slime.
In making the glue slime, some use liquid starch when borax powder is not available. Because of the unique property of the glue slime, a putty-like substance called polymer, it appears to be moving slowly, simulating the movement of a glacier.
A glacier is made up of dense ice formed from the accumulation of snow over many years. Glaciers only form on land and are characterized by constant movement under their own weight. A glacier can break to form crevasses and seracs when great pressure or stresses are applied on it. It can also appear to stretch or bend when the pressure or strain is reduced. A glacier may look like it's flowing downhill, bending like a very slow flowing river, because of the pull of gravity and the steady pressure on the mass of ice. During the winter season, glaciers store water as ice, though it's released as water when it melts during the summer season.
